"Facebook remains the primary platform for most Americans. Roughly two-thirds of U.S. adults (68%) now report that they are Facebook users, and roughly three-quarters of those users access Facebook on a daily basis. With the exception of those 65 and older, a majority of Americans across a wide range of demographic groups now use Facebook... The video-sharing site YouTube – which contains many social elements, even if it is not a traditional social media platform – is now used by nearly three-quarters of U.S. adults and 94% of 18- to 24-year-olds... Some 78% of 18- to 24-year-olds use Snapchat, and a sizeable majority of these users (71%) visit the platform multiple times per day. Similarly, 71% of Americans in this age group now use Instagram and close to half (45%) are Twitter users... Pinterest remains substantially more popular with women (41% of whom say they use the site) than with men (16%). LinkedIn remains especially popular among college graduates and those in high-income households. Some 50% of Americans with a college degree use LinkedIn, compared with just 9% of those with a high school diploma or less. The messaging service WhatsApp is popular in Latin America, and this popularity also extends to Latinos in the United States – 49% of Hispanics report that they are WhatsApp users, compared with 14% of whites and 21% of blacks."

The report was based on telephone interviews of 2,002 adults (18 years of age or older) living in the United States. The interviews were conducted during Jan. 3 - 10, 2018, and included 500 respondents via landline telephones, and 1,502 respondents via mobile phones. The survey was conducted by interviewers under the direction of Abt Associates.

Pew Research also found:

"... the share of social media users who say these platforms would be hard to give up has increased by 12 percentage points compared with a survey conducted in early 2014. But by the same token, a majority of users (59%) say it would not be hard to stop using these sites, including 29% who say it would not be hard at all to give up social media."
